When the Layers Agree: Reading Stool and Broad Protein Panels Alongside the Genome

A clinical guide to interpreting microbiome and high-plex proteomic reports — what each layer actually measures, how much weight it deserves, and why convergence across independent layers is the only signal strong enough to act on.

Imaging the Longevity Workup: What Calcium Scoring, CCTA, Whole-Body MRI, DEXA and CPET Each Buy — and What Each Costs

A practical framework for sequencing advanced imaging in preventive practice: why a picture of disease outranks a score that predicts it, where coronary calcium goes blind in younger patients, and how to weigh whole-body MRI's occult cancers against its cascades.

Genotype Sets the Hand, Bloodwork Shows How It Is Being Played: Pairing Genetic Risk With Movable Cardiometabolic Markers

A clinical guide to interpreting genetic risk alongside blood biomarkers in cardiovascular prevention — why apoB beats LDL-C, where Lp(a) fits, how to catch insulin resistance a decade early, and why a laboratory reference range is not a target.

SNPs and SNP Panels: Reading a Curated Variant Report Without Over-Reading It

A clinical guide to what common single-nucleotide variants and curated panels genuinely deliver — pharmacogenomic phenotypes, HLA risk types, polygenic percentiles — and the structural reasons a negative panel in a symptomatic patient tells you almost nothing.

HLA Typing in Practice: The Results That Prevent a Severe Drug Reaction — and the Ones That Only Rule Out Disease

A clinical guide to reading HLA results: which alleles change prescribing today, why a coeliac-permissive type is not a diagnosis, and when a genome-derived HLA call must be confirmed before you act on it.

Reading a Pharmacogenomic Report: The Gene–Drug Pairs That Actually Change a Prescription

A clinician's guide to interpreting metabolizer phenotype labels, the gene–drug pairs with evidence strong enough to act on today, and why a genotype describes capacity rather than current enzyme activity.

The 94th Percentile Is Not a 94% Risk: Reading Polygenic Scores in Cardiovascular Prevention

A practical guide to interpreting a polygenic risk score report — how the number is built, how to convert a percentile into absolute risk, why the score may not apply to your patient at all, and why a high score usually changes timing and intensity rather than diagnosis.
